    Metal Cereal?

    Not many people put a whole lot of thought into what their morning cereal is made of. Most people would just assume there's some grain and maybe a little sugar, or a lot of sugar if you're more of a Lucky Charms person than a Raisin Bran person. Nobody would suspect, though, that there would be metal in their Cheerios. Turns out, Cheerios are magnetic. Or are they? Fill a bowl with water and drop in a couple Cheerios. Take a magnet and hold it just above the Cheerios, the Cheerio will be attracted toward the direction of the magnet. Why is this? If the little cereal ring is magnetic, then
  2. During archery in gym class, I'm usually one of the people who gets my hands on the nicer quality bows. But today I was sad to find myself with one of the weaker, green bows. I had never shot with one of these bows, so when I took my first shot the same way I normally would, I was surprised to find that it fell to the ground just before hitting the target. I realized that this was simple physics, and I could easily fix my shot. The green bows have much less tension in the string than the longer wooden bows, meaning that when released, they exert less force on the arrow. So my arrow was le
  3. One of the endlessly fascinating things about physics is that it's in literally everything. Makeup is one of my primary hobbies, and I've noticed many aspects of physics in my daily routine. Whether you're using a makeup brush or a makeup sponge to get that flawless finish, you create a lot of friction on your face. In fact, the level of friction you apply will determine the quality of your application. Not enough, and you'll look a patchy mess. Too much, and you probably irritate your skin and defeat the purpose. A perfect balance of friction is what will lead you to a soft blend.
  4. Citizens of the Rochester area experienced a weather crisis of dangerous proportion a couple weeks ago, to varying degrees. When I realized the power was down,I was excited for what I assumed would be a temporary break from school, and physics, but was disappointed. My father, being a type-A scientist type, found a way to bless me with the joy of physics even during our dark age adventure. My home had no electricity for days, and therefore no heat. We do, however, have a wood stove with a blower.The blower requires electricity, and my father keeps a deep cell battery for emergencies. So
  5. Does everyone remember that day in science class when they told you the Earth was round, and you were like, "Yeah, no duh." And then a couple of years later they told you the Earth was also incredibly smooth, and you kinda just went with it. And then they said if you held an orange and a billiard ball in your hand, and then you could also hold the Earth, that it would feel more like the billiard ball than it would the orange? And that's when you got real confused. What about all the super tall mountains and super deep valleys and the trenches and the oceans? It made sense eventually though tha
  6. First of all, unpopular opinion: The Bee Movie is awesome. It's funny, and cute, and you can't go wrong with Jerry Seinfeld. But as with any kids movie, the physics are way way off. What I found interesting though, was the movie's own mention of faulty physics, in the bees and their ability to fly. People always say that bees aren't supposed to be able to fly and scientists don't know how they can, but I called baloney and looked it up. The movie begins with a line "According to all known laws of aviation, there is no way a bee should be able to fly." Which is wrong. Turns out, scientists hav
  7. To say that Doctor Who does make sense would be ridiculous, but I'm not talking about any one episode. The entire plot line of the second version just doesn't hold up. For anyone who hasn't seen DW (what are you doing with your life?) the Doctor is basically a time traveling, galaxy hopping vigilante. In the first version, the doctor traveled with all kinds of companions, including people from his home planet, Gallifrey. In the second version, the Doctor has just "returned" (emotionally and physically kinda?) from a battle called the Time War in which everyone from his planet, except for

    Egg Drop

    My little brother is in 6th grade, and has for the past week been working on the iconic egg drop project. I've been told that all 6th graders in West Irondequoit get to do an egg drop, and have heard interesting stories from friends about their experiences. I never got to do an egg drop in elementary school, so I'll admit I'm fairly bitter. But out of respect for the egg drop I'll put this aside. I have a lot of appreciation for this egg drop project, as it opens younger kids minds to physics. My brother told me that his teacher introduced the project with a demonstration. She held up a s

    Twilight Physics

    Through a series of unfortunate events last weekend, I was forced to sit through a viewing of Twilight. In all honesty, it isn't that horrible of a movie. But what I found most entertaining was the abilities of the blood suckers. You can't really critique the physics of vampires, because who can say that their insane abilities wouldn't be made possible by magic or sparkles or something? But either way, I still have questions. In the movie there's a scene where the characters play vampire baseball during a storm, as they need the thunder to camouflage the sounds of them playing. So my question
